T 0 all whom it may concern;

Be it known that. 1, Mann Fnx'rrrnn, a citizen of the United States, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented a new. and usef r. Speed-Box for Shaping-Machines and. the

Like of which the following is a specificzrv tion.

shaping machines and the like.

The principal objects of the same are to provide an improved speed box for supporting a speed change mechanism of such forms that it will have bearings for the shafts of thezspecd change mechanism as well as for the shafts of the feed device, so that it may support the speed change mechanism inside and the feed device outside, certain of said bearings being of such a. character as to assist in registering the speed box with the housing of the shaping machine, whereby the speed box may be placed in position in the most convenient and simple manner, and whereby the speed changing mechanism and feed device may be set up on the speed box at the bench all complete ready for application to the housing of the machine; also to provide such construction that the shafts of the speed changing mechanism and the feed device will be provided with gears or pinions which may pass into the housing of the shaping machine and into mesh with the crank gear therein as the parts are applied to the machine in the above described manner.

Further objects of the invention are to an improved form of speed changing mechanism and especially an improved. and etlicient device for changing the speed and to improve the details thereof.

Further objects and advantages of the invention will appear hereinafter,

Reference to be had to the accompanying drawings which show a preferred embodiment of the invention, and in which- Figure 1 is a side elevation of a shaping machine with said preferred cn'ibodimcnt. applied thereto. Fig. 2 is a rear elevation of the same. Fig. 3, a transverse sectional view of the speed box. Fig. 4: is a longitudinal sectionai view of the same on the line M of Fig. 3-, and Fig. 5, is an end elevation of a portion of the feed device.

The machine as usual comprises a housing This invention relates to a speed box fat:

10 on which is supported the driving shaft 11.

This shaft is shown as in hearings on the housing and it receives power from any desired source, and extends beyond the end at the housing into bearings l2integrally mounted on a speed box 13. This speedho'x, in addition to thebearing 12 is provided with three other sets of bearings 14, 13 and, 16, all of which. areintegral with the speed box and project, heyo1id the surfacethcreofon one end of rhosame at least. The side of the housing isprovided with a series of o 'ien'ings 17 which corerspond with the several projecting bearings l2, l4, l5 and 1h. The speed box is secured to the housing by means of bolts or in any other desired way. In the end of one of the bearings 12 is a bushing 18 for the end of the shaft 11.

".lfhe'speed changing device in its preferred form comprises a long gear 20 on the shaft, 11 and located between the bearings 12 with 'Which meshes a movable gear 21 adapted to mesh with any one of a series of gears 22. These gears are fixed to a shaft 23 mounted in the bearings 15, and two of them mesh with gears 24; and :25 loosely mounted on a shaft :26 mounted in the bearings 14:. A slidahle clutch 27 is mounted to turn with the shaft 26 and to slide back and forth so as to fix either one of the two gears 24 or 25 to said shaft, in which case power will be transmitted from the power shaft through the gears 20 and 21 and one of the gears 22 to the gear or 25, and from that to the shaft 2h. The teeth ofthe clutch 27 pref erabl'y are provided with slanting surfaces 270 to permit. them to be thrown in at full speed, but instead of making them slant all the Way back, which makes the clutching action unstable they have also flat portions 271 at the rear of the slanting portions. By this construction the advantage of quick action in throwing in theclutch is'obtained Without danger of breaking the teeth, While i at the same time'the partsmay be securely clutched together, so as to avoid any danger of accidental displacement; The speed box is provided with a cover 28 removably' fixed thereon and having pivotally mounted on it a lever 29 adapted to operate the clutch 27. This lever being supported by the cover,;is

removable therewith, and operated in a Well-known. Way.

In order to provide for moving the gear AVAILABLE COPY construction provides tits the outside to mesh with the the bottom of 21 into mesh with any desired one of the! severei gears 22 which are of diilerent sizes and are arranged in a step-like manner on the shaft, e carrier is provided having a cylindrical perforation therethrough which 0t thegeer 20. It. will be seen that as the gearflt) is the only support for this carrier, the carrier may he swung about the as a pivot and moved longi-- tudinally thereon. this carrier the gear 21 is journolcd in such position as always 7 520. The carrier has an 2 in extei'iding out through a longi tudinnl. opening; in the speed no and curved around over the pro ecting side of the same. This. arin carries a fastening pin 83 which is opergited by a knob 3 and has at spring for holding it in locked position. The speed box has a. series of perforations 36 orenged in proper pogitionto register, the gear 21. with one of the several gears 22 when the pin is in the proper hole. The carrier projects inside the speed box to a position adjacent to the row of holes 36 and is provided. with a cavity 37 into which the end of the pin projects, this cavity of course, being in line with the pin. In order to provide for conveniently locating the gear in proper position sledge 38 on the speed hot: contains notches 39 for re ceiving the web of the arm 32, each of these notches is opposite one of the perforations 36, and when the arm moves into one of the notches the pin 33 will be in position to pass through the proper?perforation 36 into the cavity 37. It will be seen that the pin in this way is provided with a support at both ends so tlhst'even a smell pin will hold the parts in proper position, and furthermore, that the ports are properly guided to place Without requiring any skilled adjustment. Power is transmitted thronghthe shaft 26 and s gear or pinion 4E0 thereon to e crank gear l-l located within the housing. The connections inside the housing may be of any Well-known form, the form which is her 11 illustrated comprising a crank arm 43 winging on a pivot so as to operate the ram 4:5 in well known manner. This rain slides in ways -16. In order to provide a large well supported bearing surface and convenient and compact means for holding the rain in position, as well as to facilitate the'application of e lubricant, the ram is provided with slides l7 having a general rectangular shaped end located in inchned position. The ways are \i-Jmped to fit said slide and each is rovided with a ledge -18 which supports a p etc 49 fastened in position and having a Wedgeshaped projecting end 50 for engaging over the inclined outer surface or the slide. This for holding the slides conveniently in position by means substanwithin the surface of the.- casing, in

. sition way-it will be seen th feed device if desired,

secured to it projection on the speed-box.

This ge: r on has a crank adapted to enga -e in a longitudinal. slot in a feed block 67. This block is pivoted on it stud 68 also mounted on the speed box, and the rotation of the gen 63 oscillates the feed block on its pivot in on obviousmnnner. ()ll the feed block is mounted a bolt- 69 on which is hung an arm 70 to which the feed rod 71 is secured. The bolt 69 is mounted on a slide 72 which is adjusted. toward and from the stud 68 by an adjusting screw 73 so as to regulate the feed. The feed rod is connected with the usual feed screw 7st in a well known "manner. The forms of the table 75, chuck 76 and parts connected therewith may be such as is well known in this art and they aroso illustrated.

In setting up the speed box and its connected parts, the speed changing mechanism is first set upin the speed box when the some is on o bench or the like, a my from the main part of the shaping machine The parts of the feed device shown in F ig. 5, except the rod 71, also may be placed in p0- zit this time. The parts of the shupcr inside the housingand shove the same being in position, the speed box is aimed alongside the frgnne and moved lIlWtH' ly in it straight line so that thepinions 40 and 60 will mesh with the teeth of the beer -11 and the rojection hearings will enter the perforations 17. The speed box is then fixed in position by means of the bolts or the like and then the shaft 11 with the gear 20 thereon and the driving pulley removed (this gear preferably being integral withthis shaft) is moved through the outside bearing 12, through the carrier 30 inside bearing 12 and the hearings on the housing.- The driving pulley may then be putinto position on the end of the shaft and s bushing 18 inserted in the outside beerin which is lame enoiwhto t: v Q I:

permit all these ports to pass through it. In this mechanism does not have to be put in place after the speed hon or housing of the shaping machine but may he set up independently and in any convenient position. In this way use, in case of any lorcakage the entirospecd box with the may be shipped independently froin the shop i of the menufscturerp at the some: ring surface for and then through the at the speed changing is mounted on the frame said shafts and within said spect in said openings,
